Great Pawn Shop Find (Eden WT800)

If I bought an amp that had the s/n, born-on-date, etc., written in MAGIC MARKER (!), you BET I'd believe the bridge at 8-ohms only warning. Like Gleason said in 'Smokey and the Bandit', " . . . . you can think about it, but don't do it . . ."
But wait, it does have speakon connections...Haha!! Great way to put it!! I will probably never forget it! Thanks

If you can get a photo of the inside of your amp, particularly the output sections that are toward the back on the sides it may be possible to determine exactly which modules are in there. A good many of the older WT800a versions were upgraded to the newer specs (bridged at 4ohms, 2ohm stable on each side, 1100w from the bridged out)

Mine is a WT800a from 2001 with banana posts that has the upgraded modules and I routinely use the bridged mode at 4ohms, but there is no labeling on the outside of the amp to let you know. The fact that you were able to run it at 4ohms and didn't release the magic smoke may mean that yours has been upgraded as well, but until you have rock solid proof you shouldn't even consider running it at 4ohms bridged again.

Just for clarity, until you 100% KNOW differently you've got an amp that is only stable at 8ohms bridged.
DO NOT RUN IT AT 4ohms!
 
In the midst of all that doom and gloom I forgot to congratulate you on one of the best bass amps ever made at a really great price!

If you're looking for way more info on the amp, you can get that and probably more than you ever thought you might want over at Invalid Link Removed. A much slower board than TB, but really a ton of useful information.

I was happy to find this today at a pawn shop and put it on layaway for $320. It appears to have been made in 2003. Looks new cosmetically. Tried it out and everything checked out. I hooked it up to my Ampeg 610hlf there and sounded sooo juicy. They let me crank it... man what a sound! Anyway looking at the back panel I saw that it had a bridge section that read 8ohms only. I tried bridging it using my cab which is 4ohms. Sounded fine. Am I risking blowing something by doing so? Do any of you know why it why this head says to bridge it at a 8ohm only?My experience with bridging other heads is that they can be bridged at 4ohms to combine for maximum power. Any thoughts? Thanks

Awesome head! Congrats.

That's great information. I will do so as soon as I get my hands on it. Do you know if there are parts available to upgrade it? That would be something I'd definitely consider.
 
Wow...That sounds like a pretty loud rig!! Aside from all this power talk, I really love the EQ possibilities this amp offers. I've been using a Harke LH1000 solely for the power and because it's simple. I've always been a plug in and play kind of guy. But as soon as I hooked up the Eden, I could tell the huge difference in tone just running it flat alone. Can't wait to gig it!!

You are going to love it. One of the cooler features of the amp is the balance knob. I have one that I can bridge to a 4 ohm load. I have two 8 ohm cabs, one with a higher wattage rating than the other. Now I can safely bridge and run a 4 ohm load, but with that, both cabs are getting the same amount of wattage. By playing it it stereo mode, and not bridge, you can use different cabs with different characteristics and be able to balance the output of each cab for a perfect blend.

BTW, that pawn shop wouldn't happen to have a D-210 XST or a D-112 XST for cheap?

Yeah that sounds really cool. I remember doing something similar back in the day with a GK 800RB but without the bridging I think. But thanks, you gave me some great ideas! And no Eden cabs unfortunately. But they do have two brand new looking Hughes and Kettener BassBase 600 heads that in eyeing....

do all eden amps have the technical info on the back panel written in sharpie?

Every amp that I've owned. Kind a reminds me of the old days at the bakery. What was in the bag was hand written on the the outside.
 
Great find at a good price.
I've had that WT800A amp plus a WT500, and a Metro Combo.
Currently still have a WT800C and a WT400, though the 400 is leaving today in a trade for an AK cab.
Just make sure that the bridge button on the front is engaged when you're bridging and disengaged when not. (Its recessed for a reason). And turn the amp off to make the change. Otherwise bad things can happen.
The only problem with these amps is that they're not idiot proof.
Don't lend it to anyone that doesn't know how to use it. (I'd rather not go into the story behind that statement, but suffice it to say that I was without it for a quite while after)
The advice to go to the Eden amps forum is spot on. Lots of good info dating back quite a while there. And you may find old manuals in the legacy section on the Eden website.
Congrats and enjoy.

I absolutely would NOT bridge that amp into 4 ohms. If your WT800 is actually a 2003 amp, it cannot bridge into 4 ohms without overheating and significantly damaging the amp - what is sometimes referred to as "releasing the magic smoke". It could quickly become a very expensive paperweight.

However the 2003 WT800 used banana plugs, not speakon connectors, so that's a bit confusing. The speakon connectors could have been an aftermarket mod as that mod was posted on the Eden forum at one time and it is not particularly difficult to do if you can use a soldering iron. I would presume this was what is known as a WT800A. It will produce 400-watts per channel @ 4 ohms and 800-watts bridged at 8 ohms. My WT500/800 was upgraded to this same power section and supply and I run it bridged into my DNS410 cab.

In mid-July of 2005 Eden released the WT800B which had an upgraded power section. It would go down to 2 ohms per channel and 4 ohms Bridged. That produced 550-watts per channel at 2 ohms and 1100-watts bridged at 4 ohms. The B model did come with speakon connectors but was clearly marked 4 ohm minimum bridged. The WT800B never appeared in an Eden catalog because it came out too late for the 2005 catalog and Eden did not put out a catalog for 2006.

In 2006, the WT800C was released with a few more cooling and circuit protection improvements along with the addition of a backlit Eden logo on the front of the amp. This backlit logo (often referred to as the "porch light") is the easy way to tell if you have the "WT800C" model. Since there was no Eden catalog in 2006, it first appeared in Eden's 2007 catalog. It also was clearly marked 4 ohm minimum bridged on the back of the amp next to the bridged output.

After Marshall bought Eden in December of 2011, they decided they were not comfortable with rating the WT800C at 4 ohms bridged and changed the text to say 8 ohm minimum bridged. Despite the fact that it had been run successfully without problem at 4 ohms bridged for 12 years, they decided to change that ohms text on the back of the amp. They made no changes whatsoever to the amp itself. WT800C amps started appearing with the 8 ohm minimum markings in mid to late 2012. I'm sure it had nothing to do with the new amp series they were working on a the time.

So, I would personally have no problem at all running a WT800C at 4 ohms bridged if the amp has the backlit Eden logo on the front. If a WT800 doesn't have that backlit logo, I would presume that the ohms rating on the back is correct and would NOT run it below 8 ohms.

For more info about your specific amp, I suggest pose your question over at the Edenamps forum along with pictures of the front of your amp while it is powered up and pictures of the rest of the back of the amp (no need to have powered up). There is a fellow by the name of Armin over there who will be able to identify it more clearly. In the meantime, DON'T run it bridged at 4 ohms.

Lots of info from you and everyone else. This has been quite educational for me. Lots to consider. Makes me want to hunt down a later version as well. Boy am I glad I ran in bridged for just a few minutes. I didn't notice any smoking or wierd smell. But I definitely learned my lesson. This is fun stuff!! Thanks again everyone!!

Where are you located?
I know where there is a WT800C for sale.
